  • Patent number: 6909104
    Abstract: A miniaturized terahertz radiation source based on the Smith-Purcell effect is provided, in which, from a focused electron source, a high-energy bundle of electrons is transmitted at a defined distance over a reflection diffraction grating composed of transversely disposed grating rods, so that, in response to oscillating image charges, electromagnetic waves of one wavelength are emitted, the wavelength being adjustable as a function of the periodicity of the lines and of the electron velocity. The elements of the radiation source, such as field emitter (1), electrostatic lens (4), beam deflector (5), grating (7) of metal, and a second anode (8), are integrated on a semiconductor chip using additive nanolithographic methods. The field electron source is constructed to project, as a wire, out of the surface, using additive nanolithography, and is made of readily conductive material having stabilizing series resistance.

  • Patent number: 6833541
    Abstract: In the present invention an optical waveguide grating sensing device for a dual-parameter optical waveguide grating sensor includes a first optical waveguide grating of a first resonant wavelength provided in a first section of an optical waveguide and a second optical waveguide grating of a second resonant wavelength provided in a second of an optical waveguide. The first and second gratings have different coefficients of rate of change of wavelength as a function of temperature and have substantially the same coefficient of rate of change of wavelength as a function of stain.
